Abstract

The toilet for a vehicle has the faeces from the toilet bowl flow into a catchment vessel so constructed that the solids are coarsely separated from the liquid. A pump is provided in the liquid section of the container which forces the liquid through an ultra filtration membrane to create a clean liquid which is collected in a flushing water container and made available for a further toilet flushing sequence. ADVANTAGE - Vehicle toilet which saves on space, weight and the consumption of water.

Description

Die Erfindung betrifft die raum-, gewicht- und wassersparende sowie entsorgungsarme Toilettenanlage in Verkehrsmitteln.The invention relates to space, weight and water saving as well as low-disposal toilet facilities in transport.

In den bisherigen Verfahren muß eine erhebliche Wassermenge in Verkehrsmitteln mitgeführt und nachgefüllt werden, um Fäkalien zu spülen. Die gleiche Menge zuzüglich der anfallenden Fäkalien muß in weiteren Behältern aufgefangen werden. Chemische und biologische Trennverfahren sind kosten- und zeitaufwendig und deshalb nicht effektiv geeignet.In previous methods, a significant amount of water must be in Means of transport are carried and refilled to remove faeces to wash. The same amount plus fecal matter must be collected in other containers. Chemical and biological Separation processes are costly and time-consuming and therefore not effective.

Ziel der Erfindung ist es, den Spülwassertank einzusparen, den Auffangbehälter enorm zu verringern und die anfallenden Flüssigkeitsmengen in Spülwasser umzuwandeln oder schadstofffrei und umweltschonend zu entsorgen sowie die zu entsorgende Restfäkalienmenge drastisch zu reduzieren.The aim of the invention is to save the rinse water tank Collect the container enormously and reduce the amount of liquid convert into rinse water or pollution-free and environmentally friendly to be disposed of and the amount of residual faeces to be disposed of reduce drastically.

Darlegung des Wesens der ErfindungState the nature of the invention

Die aus der Toilette anfallenden Fäkalien werden in einem Fäkalientank aufgefangen. Im Tank erfolgt eine grobe Trennung der Flüssigkeit von den Feststoffen. Mit einer Pumpe wird die Flüssigkeit durch die Ultrafiltrationsmembran gedrückt, die sich in einem Druckbehälter befindet. Das Permeat füllt diesen Druckbehälter, bis ein Füllstandsschalter die Pumpe ausschaltet. Bei Betätigung der Spülung an der Toilette wird Druckluft in den Druckbehälter eingeleitet, die einerseits über ein weiteres Ventil das Permeat als Spülwasser in die Toilette fördert. Andererseits wird gleichzeitig die Membran rückläufig gespült. Wenn die Flüssigkeit einen Grenzwert erreicht, kann durch Umschalten eines Ventils Permeat als gereinigtes Wasser in die Schleuse abgelassen werden.The fecal matter from the toilet is stored in a holding tank caught. A rough separation takes place in the tank Liquid from the solids. With a pump the liquid pressed through the ultrafiltration membrane, which itself is located in a pressure vessel. The permeate fills this pressure vessel, until a level switch turns the pump off. At Actuation of the flushing on the toilet is compressed air in the Pressure vessel initiated, on the one hand via another Valve feeds the permeate into the toilet as flushing water. On the other hand the membrane is simultaneously flushed backwards. When the liquid reaches a limit, it can be switched of a valve permeate as purified water in the Lock can be drained.

Claims (4)

1. Verfahren einer effektiven Toilettenanlage in Verkehrsmitteln, dadurch gekennzeichnet, daß die Fäkalien aus der Toilette in einen Auffangbehälter fließen, der so ausgebildet ist, daß die Dickstoffe sich von der Flüssigkeit grob trennen und daß im Bereich der Flüssigkeit sich eine Pumpe befindet, die das Medium durch eine Ultrafiltrationsmembran in den Behälter zurückfördert, wobei permeatseitig saubere Flüssigkeit entsteht, die in einem Spülbehälter gesammelt wird und für eine weitere Toilettenspülung zur Verfügung steht.1. The method of an effective toilet system in transport, characterized in that the faeces flow from the toilet into a collecting container which is designed so that the thick matter is roughly separated from the liquid and that in the area of the liquid there is a pump which Feeds medium back through an ultrafiltration membrane into the container, creating clean liquid on the permeate side, which is collected in a flushing container and is available for further toilet flushing. 2. Verfahren einer effektiven Toilettenanlage in Verkehrsmitteln nach Anspruch 1, dadurch gekennzeichnet, daß die aus der Toilette abfließenden Fäkalien fein zerkleinert dem Auffangbehälter zugeführt werden, wobei ohne Trennung der Dickstoffe die Fäkalien durch die Ultrafiltrationsmembran soweit gefiltert werden können, daß nur eine kleine Restmenge Feststoff mit geringer Restfeuchte möglicherweise auch in speziellen auflösbaren Wegwerfbehältern entsorgt werden muß.2. Method of an effective toilet installation in means of transportation according to claim 1, characterized, that the feces flowing out of the toilet are finely ground be fed to the collecting container, without separation the feces through the ultrafiltration membrane can be filtered so far that only a small one Residual amount of solid with low residual moisture possibly also disposed of in special, disposable, disposable containers must become. 3. Verfahren einer effektiven Toilettenanlage in Verkehrsmitteln nach Anspruch 1, dadurch gekennzeichnet, daß die Ultrafiltrationsmembran in einem Spülkasten als Druckbehälter montiert ist, der sich beim Umpumpen der Fäkalien mit Permeat füllt, bis ein Füllstand erreicht ist, bei dem die Pumpe ausgeschaltet wird, und daß beim Spülen der Toilette dieser Spülkasten mit Druckluft beaufschlagt wird, welche auch über ein Düsensystem Duftstoffe und bzw. oder Desinfektionsstoffe eindüsen kann, dabei die Spülung beschleunigt und gleichzeitig die Ultrafiltrationsmembran mit Permeat rückgespült wird. 3. Method of an effective toilet installation in means of transportation according to claim 1, characterized, that the ultrafiltration membrane in a cistern as Pressure vessel is mounted, which is when pumping the faeces fill with permeate until a level is reached, at which the pump is switched off, and that when rinsing the toilet is pressurized with compressed air, which also fragrances and or or via a nozzle system Disinfectants can inject, thereby speeding up the flushing and at the same time the ultrafiltration membrane Permeate is backwashed.   4. Verfahren einer effektiven Toilettenanlage in Verkehrsmitteln nach Anspruch 1, dadurch gekennzeichnet, daß durch ein Umschaltventil die Möglichkeit besteht, überschüssige, aber durch die Ultrafiltration gereinigte Flüssigkeit in eine Straßenschleuse abzupumpen.4. Procedure of an effective toilet installation in means of transportation according to claim 1, characterized, that there is the possibility of a changeover valve but liquid purified by ultrafiltration to pump into a street lock.
